State of Rhode island, have invented cer- 'tain new and useful"improvements in Bra'iding-lvlachines, of which the following is aspecification.

My 1 invention relates to braiding -machines and especially to thedevices for actua atin'g the stopping-mechanism to control the operationof the machine. My new device is particularly adapted for use onmachines such as that shown and described in my Patent No. 1,032,870,granted July 1 6, 1912,

in which the fabric is braided from a plu-j ra'lity of yarn supplies orcops carried in about a common axis.

Suitable engaging means are provided bepass over and under the uppercarriers 9, and the yarns as lead up from thecops 12 and merge with theyarns y to form the fabric 1). a c

The stoppin -mechanism of the machine is controlled :througha brake-ring14 which is mounted on .a flange 15 of the frame 2 and adapted to bemoved-rotatively about its axis to a slight extent to release the detentwhich controls the clutch-actuating devices. lhe rotative movement ofthe brakering 14 also acts to raise it bodily from its bearing onthefiange 15 to force its beveled face 16 intocontact with an oppositelybeveled face 17 on the turret 4, and thereby a wedging action iseffected which tends to raise the turret 4 against its bearing 18- onthe turret3. The three elements 14, 4 and 3 so are thus carried intofrictional engagement to exert a braking action to arrest the rotationof the two turrets. .The vparticu-lararis fully described in thefollowing specification, illustrated by the ac-- rangement of thesemeans is fully described in myPa-tent No. 1,008,504, granted Nov.

1 1, 1911, and need not here be further de- Figure 1 is a part-sectionalelevation :of a portion of abra-iding machine showing the scribed.

The brake-ring 14 is operated-through the medium of arms orlevers 20,spaced at intervals around its circumference and adapted to be engagedby feeder-devices on the turret 1. These latter are actuated by meanscontrolled bythe tension on the yarn g and w delivering from the supplycops 7 and '12, as later described. The arms 20 are pivoted at 21 on theflange 15 of the frame 2 and engage the ring 14 by means of scrcws22extending through slots in the arms. The upper ends of thearms 20 areformed with enlarged portions 23, bent at right angles to the mainportions and adapted to provide headsfor engagement with thefeelerdevices. The exact structu-reand arrangement of the arms 20 willbemore fully described inan application to be filed later, but for thepresent purpose it is sufficient to state that by swinging the arms ontheir pivots they act to pry the ring 14. rotatively on its bearing.This rotati-ve movement of the ring releases the detent means of theclinch-actuating device to effect the stopping of the machine, asdescribed in }ny Patent No. 1,008,504. granted Nov. 14, 1911, lastreferred to.

The'brackets 5 are formed with-upwardly projecting lugs 24 having"suitable slots in' which are pivoted bell-crank levers 25. .Qne arm26of the lever 25 reaches down tobrmgits end adjacent the head 23 onthe. arm 20, but this end is normally kept 'raised. away fromlthe latterby a coiled spring 27'he1d -ina'po'cket 28 in the lug 24. The'oppositearm 29 of-the lever 25 extends upward with its. end in close proximityto the deck of the carrier 9. Pivoted on the rim of the turret 4 is abow-shaped lever 30 having a curved cam-face on its edge 32, see Fig. 3,

and with itsrunder side adapted to bear on the end of the arm 29.0f thelever 25. When the lever 30 is depressed it acts on the lever to movethe arm 26 'down into position to engage the head 23 on the arm 20. Thelever is moved through engagement-with normally suspended a drop-wire 31which. is above the path'of'theiever' by the tension on the yarn w.When'the drop-wire 31 is the arrpwd, act 'todepress the,lever 30 to;tilt theleverz25."

The cop-holder 6 is mounted on the bracket 5 to rotate with the (pp asthe latter unwinds the yarn .and its rotation is con trolled: by

. engage .the tgeth 34 on the inside of the rim a pawl or detent 33adapted to of the base see Fig. 2. The pawl 33 is .normally held inengagement with the teeth by a'spring 86 held in a pocket 37 in a lug 38on the bracket 5. The release of the pawl to allow the cop-holder toturn, is .efl ected through a tension arm 39 having a" guide 40 throughwhich the yarn draws. The ar'm- 39 extends from a rocker-shaft or rod 41which at its lower end is formed with a lever 42.

' The lever 42 has one arm 43 adapted 'to engage the side of the pawl 33and another oppositely extending arm 44 to which is secured oneend of acoiled spring 45. The opposite end ofthes ring 45 is fastened to a lever46 which can amount of the springs tension on the arm will engagethelever" of range of'the 30,. as shown in Fig. 3, and riding oventheentirely. 7 released when released by the breakage; exhaustion orhindrance to delivery of" the yarnm, will act on the lever 30"to oper:

on the.'yarn'will swing the'arm 39' in the direction indicated by thearrow 0, Fig. 2. Such movement of. the arm' will rock the rod 41- andbring the arm of the lever 42' against the pawl '33. This-releases thepawl. 33-.from engagement with the teeth 34 .and allows the cop-holder'6 to rotate to deliver alength of-yarn as required.- When thetension onthe yarny is relieved tlie'arm 43 swings back under influence ofthe-spring 45 toallowthe pawl to again engage the teeth: on thebase --ofthe copholder and the latter is thus prevented from furtherrotation.

to prevent it from sliding outf passes through 4 with its portionunderaction of its spring 45 and= strike the To arrest-theoperation ofthe machine when the yarn catches onthe cop, becomes other cause, Iprovide the following instrumentalities: Pivoted in a lug on the under.side of the bracket 5 is a lever 61, preferably formed of'wire, withone arm 62 reaching out to engage the feeler-rod 48. The end of thearni62 is here shown as formed with a loop 63 which hooks around the elbow52 so that the'movement of the arm will effect a corresponding movementof the feeler-rod. The lever 61 also has an arm 64, the endaof whichliesadjacent the pawl 33,.see-Fig. 2.v Only a-slight*movement of thepawl 33"is required to release its toe from the-teeth on the cop-holder6' and normally this'movement does 'not aifect.

the position of: the arm 64 of the lever 61; Should the cop-holder beheld from'turning, however, after the pawl is released, as, for instanceby the. snarling or tangling of the yarn, then the arm 39 will continueits movement in the direction'indicated by the arrow a, undertheabnormal tension on the yarn. This continued movement of the arm 39causes the arm 44 to swing the pawl 33 a suflicient extent to engage thearm64 of the lever 61 and thereby move the latter in the directionindicated by the arrow .0 to slide the feeler-rod 48 into position toengage the arm 20. The mechanism operates in the ,samemanner when asnarlor tangle occurs as the-yarn leaves the cop. Anyabnormal bunch orknot in the yarn will be prevented from passing through the loop orguide 40 and the arm-39 will therefore be swung under the influence ofthe excess sive tension in the direction indicated by the arrow (1 tocauseth pawl to move the lever 61 and slide the feeler rod to. stop themachine.

The operation of the whole mechanism is as follows: It will beunderstood that the turret t rotates on the axis of the machine andcarries the feeler-devi'ces, 25 and 48 around with it. Normally, whenthe yarns w and y are delivering from the supply cops 12 and 7 undertension, the lever 25 is maintained out of range of the arms 20 by thespring 27, and the feeler-rod 4:8 is also depressed out of range bytheaction of gravity. lVhen the upper yarn w breaks, be-

.comes exhausted, or fails to deliver properly the drop-wire 31 movesdown into position to engage oneof the levers*30. The levers 30 arespaced around the rim of the turret and are equal innumber to the levers25 which correspond in number'to the lower supply brackets 5. It willalso be understood that there is the same number of uppersupply-carriers which travel onthe track of I the turret 4 in theopposite direction tothe latters rotation.- It is therefore obvious thatwhen a drop-wire on one of the upper carriers falls itwill almost instantly meet with one of thelevers 30 travelingin the opposite direction,and, as before stated, as

the wire 3]. travels over the curved edge of the lever 30 the latter isdepressed to the position illustrated by dash lines in Fig. 3.

ment which," in turn, effects the action of the stoppingandbraking.-mechanism. When a yarn from the lower supply 7 breaks or isexhausted the lever 39 is released and the'arm l-et swings back underthe action f the spring 45 to project the feeler-rod 48 into position toengage one of the arms 20. The rod 48 then coacts with the arm 20 in thesame manner as the lever 25 to stop the machine. When the yarn y ishindered from delivering, or a tangle obstructs the 'guide 40 on the arm39, the latteris moved in the direction indicated by the arrow 66 and,through the arm 43 and pawl 33, the lever 61 ismoved to project thefeeler-rod 48 into its operative position.

Itv will be seen that my invention provides a simple and efficientmechanism for operating the feeler-devices to coact with thestopping-mechanism when a yarn breaks or its delivery is impeded, andthe new. device is particularly positivegjand quick in action, thusinsuringprompii stopping of the machine upon failure of any one of theyarns.
